Remember Lee Major's truck in "The Fall Guy"?
Wasn’t that a Dodge?
The infamous intro jump was made in a 1980 GMC. They used mostly 1982's with the dual headlights after the show got going for the pretty shots. But used them as old 1977 for stunts. If you go back and watch all the episodes it's crazy how many different GMC's they used. (yes, I have the full dvd set along with Walker Texas Ranger and Dukes of Hazzard)
